Thank you for your replies. He always eats the same thing--Royal Canin for adult yorkies, and his treats are these moist and meaty treats by Purina that the breeders would give him as a puppy. I kept his diet exaclty as the breeders did, except gradually changing to adult dog food after he was neutered.
The vomit usually is that yellow/white foamy stuff. The vet did tell me yorkie tummies are very small, and sometimes if they are empty, it can make them nauseous. I do try to keep small amounts of the dry food in in his bowl, and he gets the treats as a reward for his potty. On a rare occasion, like his birthday and Thanksgiving, we decided to risk an upset stomach and give him real turkey meat. No negative reaction at all!
I just don't get it. |
